Warmer Summer Temperatures Protect a Foundation Forest Species from Insect Attack (27 September 2018)
As summer temperatures rise, the mortality of a dangerous herbivore increases, lessening its harmful impact on this eastern North American forest species...

Is there a 21st Century Warming Pause in the United Arab Emirates? (26 September 2018)
Contrary to climate model projections, it appears that the great 21st century global warming pause is alive and well in the United Arab Emirates!...

Plant Growth Database (25 September 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Soybean (Lenka et al., 2017). To access the entire database, click here.

500 Million Years of Unrelatedness between Atmospheric CO2 and Temperature (24 September 2018)
Given the plethora of historical data that now exist, there should be no more doubts regarding the ineffectiveness of atmospheric CO2 to control or drive climate change. It is simply nothing more than a bit player, whose influence has been continually overestimated by climate alarmists...

Evidence that Alpine Grasslands are Coping Well with Rising Temperatures (21 September 2018)
Despite a recent warming rate that is greater than that averaged for all of the Northern Hemisphere, there was no shift in the range of the alpine grasslands measured along the Qinghai-Tibetan Plateau over the period 2000-2014, contradicting the extinction-based contention that global warming is pushing alpine species off the planet...

The Interactive Effects of Elevated CO2 and Potassium on Wheat Growth and Yield (20 September 2018)
Regardless of whether or not potassium is adequate or deficient in the soil, rising atmospheric CO2 will boost future plant growth. And if potassium is a limiting factor, the simple application of a potassium-based fertilizer will raise growth and yields even more...

The Impacts of Elevated CO2 on the Productivity of Six Macroalgal Species (19 September 2018)
According to the results of this study, "a lower-pH ocean, according to current predictions, would enhance primary production in the studied algal species"...

Plant Growth Database (18 September 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Chickpea (Singh et al., 2017). To access the entire database, click here.

Testing Basic Assumptions of the CO2-induced Global Warming Hypothesis (17 September 2018)
According to the authors of this study, an "untrue picture" has been created that falsely paints rising atmospheric CO2 concentrations as a key driver of global warming...

The Buffering of Coastal Marine Ecosystems from Ocean Acidification (14 September 2018)
Adding CO2 via so-called ocean acidification can actually ameliorate the carbon limitation that exists in many coastal ecosystems, which addition further enhances their rates of photosynthesis and raises surrounding seawater pH during the day. And that chain of occurrences suggests that ocean acidification is not the boogeyman that many make it out to be...

Natural Variability Dominates Recent Climate Change (13 September 2018)
Statistical analyses performed on five climate reconstructions spanning the past 4000 years reveal several centennial- and millennial-scale natural oscillations that appear to dominate recent changes in climate in the Northern Hemisphere...

Elevated CO2 Alleviates the Effects of Drought on Lemon Trees (12 September 2018)
Results of this new study reveal that, as the air's CO2 concentration rises, lemon trees will "(1) use less water, at otherwise similar conditions, than today; (2) have higher water availability when drought hits; and (3) have higher carbon storage to survive through drought"...

Historically Warmer Climates Supported More Settlements in Northeast China (10 September 2018)
As illustrated in the data presented in this review, warming and warmer times are associated with good times for humanity, as exemplified by the greater number of settlements the land of northeast China was able to support under such climatic conditions, while cooling and colder times were typically just the opposite, with many significant settlement collapses...

Transgenerational Acclimation of the Manila Clam to Ocean Acidification (7 September 2018)
The offspring of parents exposed to ocean acidification preferentially extract internal metabolic carbon in energetically inexpensive calcification-relevant processes to maintain growth rates and build their shells in a comparable manner to that experienced under normal seawater pH conditions...

More Evidence Atmospheric CO2 is NOT Earth's Temperature Control Knob (6 September 2018)
A study of proxy atmospheric CO2 and temperature records from the warm Cretaceous period reveal consistently low CO2 values, as well as frequent decoupling with temperature, signaling that atmospheric carbon dioxide is not the control knob of planetary temperature that climate alarmists make it out to be...

Elevated CO2 Stimulates Both the Quantity and Quality of C3 and C4 Grasses (5 September 2018)
Both the quality and quantity of forage are important characteristics of grazing ecosystems. Fortunately, as revealed by data presented in this study, rising atmospheric CO2 concentrations stimulate both of these parameters. Thus, in the future, it can logically be inferred that grassland agricultural systems -- and the animals that rely upon them for food and nutrition -- will benefit as the air's CO2 content rises. And that is great news worth sharing!...

Plant Growth Database (4 September 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Sugarcane (Frew et al., 2017). To access the entire database, click here.

A Microbenthic Assemblage Response to Ocean Acidification (3 September 2018)
Both species richness and abundance were unaffected following 20 weeks of exposure to CO2 concentrations up to 5000 ppm (up to 20,000 ppm for abundance), suggesting significant tolerance to future projected increases in CO2 that are expected to reach only 700-1000 ppm over the next one to two centuries...
